MEANS FOR TRANSMITTING POWER.

Specification of Letters Patent.

Patented July 28', 1907'.

Application filed January 20,1906. Serial No. 242,024.

To all whom it may concern:

'Be it known that'I, JOHN M. JoY, a citizen of the UnitedStates, residing at New York, in the county of" York, State of N ew'Yorlr, have invented certain new and useful Improvements in Means for Transmitting Power, of which the following is a specification'. v

- My invention relates to means for transmitting power, and'has for its object toprovi de improved and simple means whereby power from a proper source may be transmitted to, and properly stored with r'elat ion to, an

operatingdevice, whereby the power may be utilized as desired and whereby the storage of the power to be utilized may be automatically regulated and controlled, and to these ends my'invention consists in the various features of construction arranged-and operating sub- '1. The object oiliny present invention is to provide av simple and effective'ineans whereby this general result stantially in the manner hereinafter more particularly setforth.

.Reierring to the accompanying drawings, wherein is illustrated one embodiment of my inv ention, Figure 1 is a vertical elevation of an apparatus embodying my invention; Fig. 2 is a side viewthereofi Fig. '3'is a partial plan view; and Fig. 4'is a detail. I

It is often desirable to provide an operating device wherein the power to operateit is stored under tension so that it will be u'nder constant stress, and so that when released it will furnish power to accomplish the results d'esired,'and when the power thus stored is utilized to a.

greater orlless extentit is desirable to automatically store more power ready for another operation.

The present device was particularly-designed :ior use in printing telegraph instruments, but is'obviously 'ap-. plicable to other-uses. 4

may be accomplished and whereby power from a given 4 source'can be transmitted to an operating deviceand stored, so to, speak, under:tension,causing said operating device. to be underaconstant stress ready for opera-.

tion when released for thatpurpose. 1

In the embodiment illustrated herein, A- represent the operating device or driven element which in this instance is shown in the form ofa shaft which is under stressand which maybe connected to operate any suitable or desirable device, The operation of this shaft m'ay be controlled inanysuitableway, and in the I present instance I have shown a. ratchet or-escapement wheel W,- which may be'coiitrolled in any convenient 'way, as by the ratchet or escapemeht W whereby the power stored in the driven" elernentor operating devicecan'be"i ntermittently utilized asdesired. Connected I to this driye'n element is a tension device adapted'to 1'e ceive afid' store power, and it is shown in thdpreserit instance inf the form. ota. spiral spri'ng B, one end of which is secured to the driven element or shaft Ain amp the spring and secured to the shaft as by a screw b, and the other end of the spring is connected to a worm wheel suitable way, as by the collar b connected to one end of D which is'loose on the shaft A. The source of power-or.

driving element in this instance is represented by the .part E, which in the present instance comprises a sleeve mounted on'the support or shaft F and receiving the driven element. Thismovable member'() of the clutch is shown in the form of a sleeve loose on the shaft F, and in the present instance it is provided with a worm wheel G adapted to engage the cooperating worm wheel D connected to the tension device and thereby with the driven element. I r

Some means should be provided tending to cause the eng'agemen't'di the clutch members, and when the parts are arranged in the positions show'n in Fig, 1, the weight of the movable member 0 and its .connected worm Wheel tends to cause engagement of .the clutch members, and under some conditions this is suflicient for the purposes, but preferably 1' provide additional means shown in the form' of a weighted or spring-actuated arm H,'having in the present instances friction roller h bearing on some portionoi the movable member, tending'to cause engagement of the clutch members and actuated in the present instance by a spring h mounted on a stud or beating hi, one end of the spring being secured to the collar h and the other end bearing on the arm H, as best seen in Fig. 3. The lsion of this spring can be adjusted by turning the Jllar h on its bearing 12 andsecuring it by the adjusting screw h. It is also desirable to provide means for preventing the backward rotation or movementof the movable clutch member when it is disengaged from the fixed clutch member, through the reaction of thetension device,

and when the worm wheels co'nnecting the tensiondevice and movable clutch member are provided with .teethcut at acolnparativoly steep angle, as represented in the drawing, advantage can be taken of-this construction to prevent the backward rotation or m0ve-' merit of the movable clutch member through theiiric tion of'th'e parts. When, however, this istn'otsufiicienh,

snd prcferably inactualpractice;Iprovide'additional I means. for, accomplishing-this result.. In .thefpresentinstance this means rep 'esente t1 in the pawl I which is shown as convenihiitlyattached to ths'armH, as bel eon, umed ns for' n eventing reverse motion mi, of a driven shaft, asleeve on said driven sh'eft having the gear connections with the movable clutch member and a. of a nd means {of eo'nh'olling the rutai lon oi! tension device consisting of a coiled spring connected at the di v member under the influence or the tension one end to the driven shaft and at its other end to the device.
